SAN DIEGO (AP) — Chris Johnson returned an interception 97 yards for a touchdown and Dwayne McDougle had a 35-yard fumble return for a score as San Diego State stunned previously undefeated California 34--0 on Saturday night. Jayden Denegal hit Jordan Napier on a 6-yard touchdown pass two plays after they hooked up on an 80-yard completion for the Aztecs (2-1), who rebounded two weeks after being routed 36-13 at future Pac-12 opponent Washington State. Cal dropped to 3-1.
